I've had an email saying that this is going to be cancelled due to the lack of payment method - however my card details are all on file, and have been used before.
Can anyone tell me what's going on?
This looks like it's actually related to a bug on our side that the tech team has been looking into. I've poked things for your account, and you should be good now. Sorry for any inconvenience or confusion!
Great. Thanks for sorting this.
